Is the M12 HACKZALL strong enough for pipe and conduit?

Yes. It is built for exactly that kind of work, and owners use it on copper, PVC and conduit regularly. It struggles more on thick steel or long cuts in hard wood.

How does it compare with an 18V reciprocating saw?

It is smaller, lighter and easier to use one-handed, but it has a shorter stroke and less power. For heavy demolition or thick material, an 18V saw is the better tool.

What comes in the kit?

The kit includes the saw, an M12 REDLITHIUM XC 4.0 battery pack and a charger. Blades are not included, so plan on buying them separately.

Does it use the same batteries as other M12 tools?

Yes. It runs on any Milwaukee M12 battery, so it shares packs and chargers with the rest of the M12 line.

Can it cut wood as well as metal?

Yes, with the right blade. It handles trim, PVC and light wood cutting well, but it is not meant for sustained cutting in thick lumber.

Is it a good choice for a first recip saw?

If you mostly cut pipe, conduit and material in tight spaces, yes. If you need one saw for heavy framing and demolition, an 18V model covers more ground.

What reviewers say

Owners rate the HACKZALL highly as a compact one-handed saw for pipe, conduit and tight-space cuts, and many praise the brushless motor and the kit battery. The common complaints are that it is slower than an 18V saw on thick material and that blade changes take a tool.

What people mention

One-handed usePraisedOwners say the single-hand grip makes cuts in tight spaces and overhead far easier than a standard recip saw.
PowerMixedReviewers find the brushless motor strong for its size but noticeably slower than 18V saws on thick or hard material.
WeightPraisedIts light weight is repeatedly called out as a plus for extended overhead work.
Blade changesCriticisedChanging blades takes a tool, which owners find slower than quick-change systems on other saws.
Battery runtimePraisedThe included XC 4.0 pack is seen as giving better runtime than the compact batteries bundled with many M12 tools.
